BUNCH-ARRESTING YARN-GUIDE FOR SPOOLI[\lG-IVIAGHINES.

To (l/ZZ whom, it puny concern:

Be it known that I, FREDERIQ W. EASTON, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Bunch-Arrestin gYarn-G11 ides for Spoofing-Machines, of which the following is aspecification.

My invention relates to improved means for preventing the winding ofimperfect yarn onto the spool, and it consists in the improvedconstruction of a bunch-arresting yarirguide, attached to thetraverse-rod, and adapted to receive the yarn from the traverse-rod andguide it onto the spool.

In the accompanying draw-rings, Figure 1 represents a top view of myimproved yarnguide. Fig. 2 represents an end view of the same. Fig. 8represents a side view showing the jaws in their closed condition. Fig.4 represents the same view with the jaws in their opened condition. Fig.5 represents a vertical section taken in the line 5 5 of Fig. 1.

In the drawings, A represents the traverserod of a spooling-machine,towhich the buncharresting yarn-guides are attached, the said yarn-guidesconsisting of a holder 13, provided with a set-screw c, for attachmentto the rod A, the said holder being provided at one side with anelongation which forms the stationary jaw C, which is providedwith theinclined edge a at its outer end and with the ear to which is pivotedthe movable upper jaw D, the said jaw being actuated to close upon thestationary jaw O by means of the spring (I, which is held in a recess 6,made in the middle portion of the ear I). At the base of the jaw D isformed the boss f, to which is attached the pin which serves to limitthe lateral movement of the yarn as it is being run onto the spool.

The movable jaw D is provided with the opposite ears h 71 which embracethe opposite sides of the ear I) of the holder and are secured theretoby means of the pivot 2'. The movable jaw D is also provided with theprojecting arm j, by means of which it may be raised from its normalclosed position with the jaw G against the closing action of the springd, as shown in Fig. 4, and with an adjusting-scrcm' k, by means of whichthe width of the elongated opening up, between the parallel jaws O andI), may be adjusted to adapt the device for spooling different 5 5grades or sizes of yarn, the projecting lug n, upon the holder B,forming a bearing-seat for the lower end of the screw it.

In order to prevent the operator of the machine froni readily tamperingwith the adj ust- 6o ment of the yarn-guide, as they are liable to do inorder to avoid the trouble of piecing the broken ends, the head of thead j listing-screw k is placed in a chamber 0, which upon the properadjustment of the opening on may be 6 5 sealed, thus providing a checkagainst the dishonesty of the operator. The movable jaw D is alsoprovided with the downwardly-inclined edge p, which serves to assist inthe rapid threading of the guide.

In the manufacture of the yarn-guide itis necessary that the jaws G andD be ground, so that the sides of the opening m between them will .beperfectly parallel with each other and in order to eii'ect this properlyit 75 is necessary that the pin 9 be inserted subsequent to the grindingof the engaging surfaces. The said separately-formed pin is therefore avaluable feature of my improvement.

The yarn to be wound upon the spool first passes over the surface of thetraverse rod A, and then through the opening m, between the horizontaljaws C and D, and thence passes to the spool 5 and when a bunch orenlarge- 8 5 ment of the yarn arrives at the opening on, the said bunchor enlargement will be arrested, and the thread will be broken betweenthe said jaws and the spool, so that the imperfect yarn will not bewound thereon. The opera- 9o tor of the machine can then, by raising thejaw D, as shown in Fig. 4, release the yarn from the opening m, andreadily remove therefrom an impediment to the subsequent proper passageof the yarn therein. 9 5

It will he noticed from Fig. 1 that the device, considered as a whole,is of right-angular form, the jaws extending lengthwise of thetraverse-rail and the forked holder extending across the same.

I claim as my invention- In combination in a yard-guide, the holder Bhaving a fork adapted to be clamped to the traverse-rod transverselythereof and having a rigid jaw extending at right angles from pin gcarried by one jaw at the inner end the fork and longitudinally of thetraverse thereof and extending across the joint he- Io rod, the movablejaw extending longituditween the jaws, substantially as described. nailyof the traverse-rod and having a right- 1 1 w I T w I angular portionextending transversely of the B REDBRHJ EASTO\ traverse rod and pivotedto the forked holder \Vitnesses:
